DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof device, and more particularly to a sunroof device in which a pseudo full-closed position exists in a range of forward and backward movement of a lid.

[0002]

2. Description of the Related Art A sunroof apparatus for an automobile has a structure in which a lid that moves back and forth is provided at an opening formed in a roof, and the opening is opened and closed by the lid (Japanese Utility Model Publication No. 8-5852 discloses a similar technique). reference). As the form of the lid moving back and forth, the fully closed position closing the opening,
There is a fully open position where the opening is opened by being housed in the roof behind the opening, and a tilt-up position where the rear end is raised above the opening. Conventionally, the fully closed position is located at the center of the forward and backward movement range of the slider for controlling the lid, and the slider is moved to the front side to be in the tilt-up position, and is moved to the rear side to be in the fully opened position.

[0003]

However, in such a conventional technique, the lid, which is required to maintain the strictest position in the front-rear direction in order to secure watertightness and prevent wind noise, is required. Since the fully closed position was set at the center of the front-back movement range of the lid, it was difficult to obtain a stable state of the lid, and high precision and rigidity were required to maintain the position of the lid. In other words, the center position in the front-to-back movement range of the lid is an unstable position where the lid can move forward and backward, so a position holding mechanism in both directions is required,
It has high accuracy and rigidity, and its structure is complicated.

Therefore, a novel structure is considered in which the fully closed position is changed to the front end in the front and rear movement range of the lid, the tilt up position is provided at the center, and the fully open position is provided at the rear end. With this configuration, a stable position holding state in the front-rear direction of the lid can be obtained only by abutting the lid against the front end of the opening.

However, in such a novel structure, the lid is at a flap position in which the rear end is lowered from the opening immediately before reaching the fully open position, and then slides rearward to the fully open position. There is a pseudo-fully closed position in which the lid temporarily closes the sunroof opening between the and the tilt-up position.

The auto switch for controlling the opening and closing of the lid can obtain a fully closed position, a tilt-up position, and a fully open position each time the switch is pressed. The lid stops. Therefore, there is a risk that the occupant may mistakenly set the pseudo fully closed position as the original fully closed position and press the switch there to stop the lid.

The present invention has been made in view of such circumstances, and provides a sunroof device capable of preventing an erroneous stop operation of a lid due to erroneous recognition.

[0008]

According to the first aspect of the present invention,
A lid that can open and close the opening formed in the roof of the vehicle body,
A slider connected to the lid and moving back and forth on a side rail provided on the vehicle body side; a fully closed position in which the slider is moved forward and the lid closes the opening at the foremost position; and an initial stage of rearward movement of the slider. The rear end of the lid is raised above the opening, the flap position where the rear end of the lid is lower than the opening by moving the slider further rearward, and the slider is further moved rearward through this flap position. As a result, the lid moves between each position and the fully open position where the opening is completely opened, the front and rear movement of the slider is automatically obtained by the drive unit, and the opening is temporarily closed by the lid between the tilt-up position and the flap position. A sunroof device having a pseudo-fully-closed position that is partially closed, wherein the lid does not stop at the pseudo-fully-closed position when moving in the opening direction and the closing direction. There is a.

According to the first aspect of the present invention, the lid is
When the vehicle is moved in the opening direction and the closing direction, the vehicle cannot be stopped at the pseudo fully closed position, so that there is no possibility that the occupant will stop the lid at the pseudo fully closed position by mistake. In an auto-type switch in which the lid moves to a predetermined position by one-touch operation, the lid passes through the pseudo fully closed position without stopping. Even if the lid is forcibly stopped by pressing the switch again in the pseudo fully closed position, the switch operation in the pseudo fully closed position is invalidated.

According to a second aspect of the present invention, the drive unit can detect the position of the lid based on the count number from the reference point, and the lid cannot be stopped at the pseudo-fully closed position of the lid.

According to the second aspect of the present invention, since the drive unit can detect the position of the lid based on the count number from the reference point, the pseudo fully closed position of the lid can be accurately recognized, and the position can be recognized. Switch operation can be reliably disabled.

According to the third aspect of the invention, the lid stops at the tilt-up position when moving in the opening direction, and does not stop at the tilt-up position when moving in the opposite closing direction.

According to the third aspect of the present invention, when the motor is moved in the opening direction, it stops at the tilt-up position, but in the opposite closing direction, it does not stop at the tilt-up position but moves to the fully closed position. Therefore, when the occupant operates the switch to close the lid, the lid is not left in the tilt-up position due to erroneous recognition and does not leave the vehicle.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. 2 to 6
In the figure, a part of each part is shown transparently for convenience of explanation.

An opening 2 for a sunroof is formed in a roof 1 of an automobile. The lid 3 is movable back and forth, and opens and closes the opening 2. On both left and right sides of the opening 2 and below the roof 1, side rails 5 of extruded products formed symmetrically are arranged.
At the front of the opening 2, a motor 6 as a "drive unit" is provided. The motor 6 is capable of detecting the position of the lid 3 based on a count number using a fully closed position of the lid 3 described later as a reference point. Cables 7 (FIG. 7) are routed from the motor 6 into the left and right side rails 5. The cable 7 is engaged with the gear of the motor 6, and can move in the left-right direction simultaneously in the front-rear direction according to the rotation of the motor 6.

The side rail 5 is provided with a slider 8 and a hook 10 which move back and forth together with the cable 7 while being connected to the cable 7. A guide pin 11 is provided at the upper end of the slider 8.

On the other hand, guide members 12 extending in the front-rear direction are fixed to the lower surfaces of both right and left ends of the lid 3 so as to move back and forth integrally with the lid 3. The guide member 12
The rear side is rotatable up and down around a front leg (front end) 13 engaged slidably back and forth in the side rail 5, and the rear leg 14 is detachable from the hook 10 from the front. It has become.

A cap member 16 made of resin is fitted into the guide member 12 at the center thereof. When viewed from the side (in the state of FIG. 2), the cap member 16 has a substantially inverted “H” -shaped guide groove 17 formed in a non-penetrating state. A guide pin 11 formed at the upper end of the slider 8 is movably engaged with the guide groove 17.
As described above, the guide groove 17 is formed in the resin cap member 16.
Is easier to process than when it is formed directly on the metal guide member 12. Also, the guide pin 11
Is in contact with the resin, so that the sliding resistance is small and the movement of the guide pin 11 becomes smooth. Further, the cap member 18
Since the guide groove 17 is non-penetrating, the rigidity of the cap member 16 does not decrease.

Next, the actual movement of the lid 3 will be described with reference to FIGS. First, when the driving force of the motor 5 is transmitted to the slider 8 via the cable 7 and retracted from the fully closed state (FIG. 2), the guide pin 11 of the slider 8 moves from the front end of the guide groove 17 to the middle. Then, the lid 3 is in the tilt-up position (FIG. 3).

Next, when the slider 8 is further retracted,
The lid 3 does not stop at the pseudo fully closed position (FIG. 4) where the opening 2 is momentarily closed, and after passing through the pseudo fully closed position, the guide pin 11 hits the rear end of the guide groove 17 and the lid 3 At a flap position lower than the opening 2 (FIG. 5).

When the slider 8 is further retracted while the guide pin 11 is engaged with the rear end of the guide groove 17, the lid 3 is fully opened with the opening 2 completely opened (FIG. 6).

When the slider 8 is moved in the closing direction, the lid 3 moves in the reverse order, and returns to the fully closed position.

In each of the above states, the position automatically obtained by operating the switch is, as shown in FIG. 8, three positions in the open direction: a fully closed position, a tilt-up position, and a fully opened position. In the direction, the tilt-up position is also omitted, and the full-open position is immediately returned to the fully-closed position.

That is, when the lid 3 is moved in the closing direction, it cannot be stopped at the pseudo fully closed position. In this embodiment, an auto-type switch is used in which the lid 3 automatically moves to a predetermined position by a one-touch operation, but the lid 3 always passes without stopping at the pseudo fully closed position. Attempting to forcibly stop the lid at the pseudo fully closed position by pressing the switch again at the pseudo fully closed position invalidates the switch operation at the pseudo fully closed position. By doing so, the occupant mistakenly inserts the lid 3
Is completely prevented from stopping at the pseudo fully closed position.

The lid 3 stops at the tilt-up position when moving in the opening direction, but does not stop at the tilt-up position in the opposite closing direction.
When the switch is operated to close the lid, the lid 3 is left in the tilt-up position due to erroneous recognition and does not leave the vehicle.

[0026]

According to the present invention, the lid cannot be stopped at the pseudo fully closed position when moving in the opening direction and the closing direction, so that the occupant accidentally stops the lid at the pseudo fully closed position. There is no fear. In an auto-type switch in which the lid moves to a predetermined position by one-touch operation, the lid passes through the pseudo fully closed position without stopping. Even if the lid is forcibly stopped by pressing the switch again in the pseudo fully closed position, the switch operation in the pseudo fully closed position is invalidated.
